Compound TPU/Thermoplastic Polyurethane Tpu Granules/compounds for Wire and Cable

Thermoplastic polyurethane elastomer (TPU) is a kind of elastomer that can be plasticized by heating and dissolved by solvent. It has excellent comprehensive properties such as high strength, high toughness, wear resistance and oil resistance. It has good processing performance and is widely used in national defense, medical, Food and other industries. Thermoplastic Polyurethane has two types: polyester type and polyether type, white random spherical or columnar particles, and the density is 1.10~1.25g/cm3. The relative density of polyether type is smaller than that of polyester type. The glass transition temperature of polyether type is 100.6~106.1℃, and the glass transition temperature of polyester type is 108.9~122.8℃. The brittleness temperature of polyether type and polyester type is lower than -62℃, and the low temperature resistance of polyether type is better than that of polyester type. The outstanding features of polyurethane thermoplastic elastomers are excellent wear resistance, excellent ozone resistance, high hardness, high strength, good elasticity, low temperature resistance, good oil resistance, chemical resistance and environmental resistance. The hydrolytic stability of the ester type is much higher than that of the polyester type.
